From the crunchy nut crust to the creamy custard layers, these simple components come together effortlessly to create a dessert you’ll want to make again and again.
- 1 cup flour: Provides the structure for the crust, giving it a tender base.
- 2 tablespoons sugar: Adds just enough sweetness to the crust without overpowering it.
- 1/2 cup butter, melted: Binds the crust ingredients and adds rich flavor and moisture.
- 1/2 cup macadamia nuts, finely chopped: Introduces a buttery crunch; cashews or pecans work well too.
- 6 oz cream cheese, softened: Creates a luxuriously smooth and tangy cheesecake layer.
- 2/3 cup powdered sugar: Sweetens the cream cheese layer gently and dissolves smoothly.
- 2/3 cup whipped topping: Lightens the cheesecake filling to make it delightfully airy.
- 1/2 teaspoon vanilla extract: Enhances the cream cheese flavor with a warm aromatic note.
- 2 tablespoons cornstarch: Thickens the key lime custard to a luscious, spoon-coating consistency.
- 3/4 cup key lime juice: The star ingredient providing that unmistakable sharp and zesty lime flavor.
- 3/4 cup sugar: Balances the tartness in the custard layer beautifully.
- 4 egg yolks, slightly beaten: Gives richness and helps set the custard.
- 5 tablespoons butter: Melted into the custard for richness and a velvety texture.
- Green food coloring (optional): Adds a fun, vibrant touch reminiscent of classic key lime pie.
- 1 1/2 cups whipped topping: Folded into the cooled custard to keep the flavor light and fluffy.

How to Make Key Lime Pie Lasagna Recipe
Step 1: Prepare the Nutty Crust
Start by preheating your oven to 350°F (175°C) and greasing a 9×9-inch baking dish. In a medium bowl, combine the flour, sugar, melted butter, and finely chopped nuts. Mix until the texture is crumbly and holds together when pressed. This crust will provide a buttery, crunchy foundation full of subtle nutty flavor. Press it evenly into the bottom of your pan and bake for about 20 minutes until golden. Set it aside to cool completely before moving on to the next layer.
Step 2: Make the Cream Cheese Layer
While the crust cools, beat the softened cream cheese and powdered sugar until smooth and creamy. Folding in a cup of whipped topping and the vanilla extract adds an essential lightness and richness that creates the perfect cheesecake layer. Spread this smooth mixture evenly over your cooled crust, then chill it in the fridge to let it set while you prepare the lime custard. This cooling step is key because it helps the layers stay beautifully distinct.
Step 3: Cook the Tangy Key Lime Custard
Now for the bright heart of the dish: whisk together the sugar and cornstarch in a saucepan. Stir in the fresh key lime juice and the slightly beaten egg yolks. Add the butter and gently simmer the mixture over medium-low heat, stirring constantly until thick enough to coat the back of a spoon. This slow cooking thickens the custard perfectly without scrambling the eggs. Remove the pan from heat, cover the surface with plastic wrap to prevent a skin from forming, and chill in the fridge for at least two hours until fully cooled. Optionally add a few drops of green food coloring for that classic key lime pie look. Once chilled, fold in 1 1/2 cups of whipped topping and spread this verdant, velvety layer over the cheesecake base.
Step 4: Top with Whipped Cream and Nuts
For the final touch, gently spread 1 cup of whipped topping over the key lime custard layer. This creamy top layer balances the tartness underneath beautifully. If you love a bit of texture, sprinkle the top with chopped nuts for a subtle crunch and a lovely presentation. Now, your almost-ready Key Lime Pie Lasagna Recipe is just waiting to chill and set fully.
Step 5: Chill to Set and Serve
Refrigerate the entire dessert for at least 4 to 5 hours, preferably overnight. This resting time allows the flavors to meld and the layers to firm up to a luscious, sliceable consistency that is both creamy and refreshing. Alternatively, you can freeze this dessert and serve it partially thawed for a frozen delight. It will defrost quickly and maintain its creamy texture, offering you flexibility in preparation.

Garnishes
A simple garnish can elevate the Key Lime Pie Lasagna Recipe from stunning to show-stopping. Fresh lime zest or thin lime slices add a fresh burst of citrus aroma and a pretty pop of color. A sprinkle of finely chopped macadamia nuts or other crunchy nuts also enhances texture and complements the nutty crust. For extra visual contrast, a few mint leaves can be tucked on top for a refreshing green accent.
Side Dishes
This dessert pairs wonderfully with light accompaniments like a fresh fruit salad or a scoop of vanilla bean ice cream. The cool creaminess of the ice cream contrasts with the tartness of the key lime layers perfectly. For a party spread, offer some crisp coconut cookies or biscotti alongside to add a delightful crunch that complements the creamy layers of the lasagna.
Creative Ways to Present
To impress guests, try serving this Key Lime Pie Lasagna Recipe in individual clear glasses or mason jars so the beautiful layers show through. Layer with some additional lime zest or edible flowers on top for a pretty presentation. Another fun idea is to create mini versions using small square molds or cupcake liners for bite-sized indulgences perfect for potlucks or celebrations.
Make Ahead and Storage
Storing Leftovers
Leftover Key Lime Pie Lasagna Recipe keeps well in the refrigerator for up to 3 days. Cover it tightly with plastic wrap or store in an airtight container to preserve freshness and prevent it from absorbing other fridge odors. The flavors often deepen nicely with a little extra chilling, so don’t hesitate to make it the day before your event.
Freezing
This dessert freezes beautifully, making it a great make-ahead option. Wrap the baking dish securely with foil and plastic wrap to avoid freezer burn. Freeze for up to 1 month. When ready to enjoy, thaw overnight in the refrigerator. This way, you have a refreshing dessert ready whenever you need it without any last-minute fuss.
Reheating
Since this is a chilled dessert, reheating is not recommended as it may affect the texture and taste. Simply allow the frozen dessert to thaw sufficiently in the fridge, or serve it slightly frozen for a cool, refreshing treat similar to a semifreddo. Enjoy the creamy layers at their best cold and fresh!
FAQs
Can I substitute regular lime juice for key lime juice?
Absolutely! While key lime juice offers a unique tartness and aroma, regular lime juice can be used as a convenient substitute and still delivers a bright citrus flavor that works wonderfully in this recipe.
What can I use instead of macadamia nuts?
If macadamias aren’t your thing or if you have allergies, substitute them with cashews, pecans, or even almonds. Just be sure to finely chop the nuts to maintain the ideal crust texture.
Is it necessary to use food coloring in the custard layer?
Not at all! The green food coloring is purely optional and just adds a fun visual flair. The key lime custard will taste fantastic without it and have a natural pale yellow color from the egg yolks.
Can this dessert be made gluten-free?
Yes, by using a gluten-free flour blend instead of regular flour, and ensuring your whipped topping and other ingredients are gluten-free, you can adapt this recipe to suit a gluten-free diet without sacrificing flavor.
How long does the Key Lime Pie Lasagna Recipe take to set properly?
For the best texture and flavor, it’s important to refrigerate the assembled dessert for at least 4 to 5 hours, though overnight chilling is ideal. This allows each layer to firm up perfectly and the flavors to meld into a luscious harmony.
